M2eclipse Plugins for JBoss Developer Studio Beta2: network connection problems

Hi,
I tried to install m2eclipse plugins for my JBoss Developer Studio Beta2 but keep getting the error. I tried allowing this in the firewall and still it could not connect. Is this because of a poor connection speed or is it the installer’s problem?
